Familial lumbar Scheuermann disease with idiopathic scoliosis in China: First case report

Atypical Scheuermann's disease with severe kyphosis and negative sagittal balance in the thoracolumbar region: A case report and literature review

INTRODUCTION AND IMPORTANCE

Scheuermann's kyphosis is a structural deformity of the thoracolumbar spine that is classified in typical (thoracic) and atypical (lumbar and thoracolumbar) Scheuermann's disease. Surgical intervention is reserved for those with progressive kyphosis, intractable pain and neurological impairment. Although, previous literature focuses on the correction of the thoracic kyphosis (TK), recent lines of evidence recommend considering all the sagittal balance parameters when performing a surgery. We herein, report a posterior-only approach in a patient with Scheuermann's kyphosis, considering all the sagittal balance parameters.

CASE PRESENTATION

The patient was a 17-year-old boy with a kyphotic deformity in the lumbar region, with urinary retention and upper back intractable pain. The preoperative physical examination was normal except for a kyphotic gait. The patient was first treated with thoracic lumbosacral orthoses (TLSO) brace that was not effective; consequently, the patient underwent posterior only approach (pedicular screw fixation along with Smith-Peterson osteotomy) with correction of the sagittal balance and kyphosis. The patient's sign and symptoms improved significantly. The surgery was uneventful and no complication was recorded. The 1-year follow-up revealed normal neurological examination and normal sagittal balance parameters.

CLINICAL DISCUSSION

Atypical Scheuermann's kyphosis with neurological impairment and progressive kyphosis should be treated with surgical intervention.

CONCLUSION

Considering the sagittal parameters of the spine, the surgical intervention should be designed to correct the kyphosis and the other indices of the sagittal balance. Posterior-only approach is safe and effective method for correction of the TK and improving the signs and symptoms of the patients.

Scheuermann's Disease in Young Adults: A Case Report

Scheuermann kyphosis, also known as Scheuermann disease, juvenile kyphosis, or juvenile discogenic disease, is a condition involving an abnormal, excessive curvature of the spine. It involves both the vertebral bodies and discs of the spine and is characterized by anterior wedging of greater than or equal to 5 degrees in three or more adjacent vertebral bodies. Type 1 Scheuermann's disease involves the thoracic spine, whereas type 2 involves both the thoracic and lumbar spine. Although no definitive cause for Scheuermann's disease has been found, we have reported a case that may explain further about this disease. This article elucidates a case of a 19-year-old boy experiencing pain in the lower back and showing various signs and symptoms of Scheuermann's disease and the diagnosis and steps taken by doctors toward its treatment.

A Case of Scheuermann’s Disease Co-Occurrence with Idiopathic Scoliosis and Intradural-Extramedullary Epidermoid Cyst: The First Case Report in Literature

Background and importance: Scheuermann’s disease (SD), intradural-extramedullary epidermoid cysts and idiopathic scoliosis (IS) are all rare conditions. The co-occurrence of the three condition on one case has not been reported in literature before. We describe an extremely rare case of SD co-occurrence with IS and intradural-extramedullary epidermoid cyst, which is the first in the literature. Clinical presentation: A 13-year old boy and his parents presented at Honghui Hospital complaining of progressive hyperkyphosis for 5 years and back pain for 2 months. Thorough medical examination and radiology confirmed the diagnosis of SD kyphosis, IS, and intradural-extramedullary epidermoid cyst. Medical panel with spine surgeons, oncologists, neurosurgeons, histopathologists and radiologists were consulted. Tumor excise, kyphosis recorrection and spine reconstruction surgery was conducted. Postoperative histological examination detected desquamation of keratin from the epithelial lining and stratified squamous epithelium without skin adnexa. The boy was ambulant 2 days postoperative with walking aids. Conclusion: This is the first case report of Scheuermann’s disease (SD) co-occurrence with idiopathic scoliosis (IS) and intradural-extramedullary epidermoid cyst. The co-occurrence of intradural epidermoid cyst, SD and IS might not be a coincidence, indicating a kind of genetic etiology need to be illuminated.
